The Semi-Heavy Size Jolt (joint-saving power hit)

Q: I got your Power-Density Mass Workout 2.0, and I really like the 3-way split of the Basic Workout. I also like doing only one or two exercises for each muscle with a power hit and a density hit at the same workout. My question is, I’m 48 years old and not sure I can handle pyramiding down to 5 reps on big exercises, so should I just do regular 8-rep sets to failure? These days my joints don’t like anything below 8 on most exercises.

A: That’s a good solution. For example, on chest-supported dumbbell rows for mid-back, your set sequence would be…

Fast Moves to Get You Huge?

Steve spotting Jonathan on DB shoulder presses - Fast Moves to Get You Huge?

Q: I was reading one of your newsletters I saved, and you were talking about how bad it was to see people using fast moves with ballistic reps in the gym. But I’m pretty sure I’ve seen you guys recommend fast reps recently. What’s the deal—are they good or bad?

A: There is research showing that a faster tempo can help engage more fast-twitch growth fibers; however, our speed, or X-celeration, method is not throwing the weights… [Read more…]

Shocking New Muscle Mass: TORQ – DP 4X – Modified Pre-Ex

Lateral raises - Shocking New Muscle Mass: TORQ - DP 4X - Modified Pre-Ex

Q: I do four-week phases of different workouts from your various e-books. That strategy works great for me. I’ve gained 10 pounds of muscle in three months, and that’s after training consistently for 10 years. I’m getting ready to start the Modified Pre-Ex 3X Mass Workout. After all the positive talk about TORQ, I was thinking about using that on the first exercise, the isolation move. Is that a good idea for building new muscle mass?

A: Absolutely. We’ve talked about that before, and we used to use TORQ-ed up modified Pre-Ex as a shock tactic in our old Freaky Friday workouts… [Read more…]

Take Your Pick to Get BIG Quick—2 Ways to Grow

Squats (top position with ripped abs) - Take Your Pick to Get BIG Quick—2 Ways to Grow

Q: I’m reading the Super-Size e-book. Jordon’s 18-pound muscle gain is inspiring and a great story, but I’m 45 years old. He’s in his teens. I don’t think I can train heavy even at every other workout the way he did. Should I try it, even at my age? I got great gains with The Anabolic After-40 Muscle-Size Manual, but this one has me intrigued to see if I can get big during my next training phase.

A: Well, glad you’re immersed in and inspired by The Super-Size Crash Course, but you should keep reading. Chapter 6 lays out a great alternate Phase 1 program—without heavy pyramids… [Read more…]

Triple-Threat Mass-Building Sets (use with caution)

Jordon Williamson before and after - Triple-Threat Mass-Building Sets (use with caution)

Q: I’ve been training for about 20 years now (I’m 44), and I am getting my 14-year-old son into it. He’s been working out about four months, breaking in, but I still do NOT want him to go “heavy.” I have him using your 4X method, which is great at his stage. I was thinking about the Progressive-Speed 4X version as well, specifically the speed set in order to help build the power fibers. Is that a good idea at his age, or should he use with caution?

A: First, what you have him doing now is perfect. Moderate-weight growth-threshold 4X is fantastic for young teens getting into lifting. Heavy weights may damage young joints early on, so it’s a good idea to get neophytes gradually acclimated… [Read more…]

Amplify the Mass Effect? New Look at Key Muscle-Size Study

Muscle Quick Start and New Change to Gain

Goodin bench press

Q: I’ve been using your Quick-Start Muscle-Building Guide for a few months in hopes of some change to gain, and I have never looked better. I did not know I could change my body this fast. I now have my teenage son starting with the Quick-Start Fast-Mass Program. He loves it and is growing quickly, but my question is about me. Considering my age, 47, can I and should I transition to using the 4X mass method on that workout? I’m getting strong and worried about joint damage.

A: Absolutely. The Quick-Start Fast-Mass Program is a great two-way split on which [Read more…]

Speed sets and muscle growth—key exercise exceptions

Behind-the-neck presses - Speed-sets muscle growth—key exercise exceptions

Q: I tried DP 4X (downward-progression 4X) on my big midrange exercise with a speed drop set after the last one. Wow, what an amazing feel and pump. I do behind-the-neck presses for delts. Can I use speed sets on those too if I’m careful?

A: You could—but you may end up needing rotator cuff surgery… [Read more…]

Last-set variation for extreme mass creation

Wide pulldowns

Q: I’ve been using TORQ in my workouts, usually on my last isolation [or contracted-position] exercise. What a big difference. I usually do 30, 20 and 15 reps, then on the last I do a drop set or a double drop. Crazy pump. My question is, should I use the drop or double drop on the last set of my DP 4X sequence as well? I do that on the big midrange exercise, like pulldowns [12, 10, 8, 6–adding weight on each set, 40-second rests between sets].

A: You can use a drop or double drop on the last set of a TORQ, DP 4X or standard 4X sequence. It’s just one more way to get extra volume and overload for extreme mass creation… [Read more…]

High-End Hypertrophy With a Density Edge

Hammer curl vascular arm

Q: I have used 4X with 10 reps per set, but I see you’ve also used 15 to 20. Does that work? Will it get me bigger and more vascular? Is it better than standard TORQ [30-20-15]?

A: It’s really just another variation—semi-TORQ, if you will, but without a poundage increase on each set. It’s high-end hypertrophy with a density edge. [Read more…]
